It is a 3+N-pole unit for 400 V systems, carrying a short-time-delayed G characteristic — meaning it tolerates brief transient leakage currents without nuisance tripping, which is useful on circuits with electronic loads that produce a start-up pulse. ## Panel integration This is a DIN-rail-mount residual current device, 4-module width (4 MW per the description), designed for snap-on installation in distribution boards and sub-distribution panels. The short-time-delayed G characteristic supports selective coordination with downstream RCDs, reducing the risk of a single fault taking out an entire sub-main.","metaTitle":"Siemens 5SV3344-6MJ01 RCCB Type A, 40A 30mA 10kA, 4-pole","metaDescription":"Siemens 5SV3344-6MJ01 residual current circuit breaker, Type A, 40A, 30mA, 10kA, 3+N-pole, 400V, short-time-delayed G.
